Description

Technical Field

[0001] The present invention belongs to the technical field of marine equipment, and in particular relates to a mooring device for marine tugboat cables. Background Art

[0002] With the booming development of the marine economy, marine tugboats are increasingly widely used in fields such as port operations, maritime rescue, and ship transfer. In these operation scenarios, the quality of the mooring operation between the tugboat and the target ship is directly related to the success, failure, and safety of the task.

[0003] However, the traditional mooring device for marine tugboat cables still has the following problems in the use process: On the one hand, its anchoring method is relatively single, usually only connecting the cable through a simple single point or a few fixed points, which makes the fixation between the marine tugboat and the target ship not firm enough. Under the action of a complex marine environment, such as strong winds and huge waves, the target ship is prone to shaking and displacement, and even the cable may break, seriously affecting the operation safety and efficiency; On the other hand, the existing mooring device cannot be adaptively adjusted according to the changes in the marine environment. When the marine environment is harsh, such as in the face of strong winds and waves, the load borne by the mooring device will increase sharply, but the traditional device cannot timely adjust the layout and tension of the cable, easily causing damage to the device; when the marine environment is relatively stable, it cannot optimize the force condition of the cable, making the traction force of the tugboat unable to be efficiently transmitted to the target ship, resulting in energy waste; In addition, during the process of adjusting the cable distance, it is difficult for the traditional mooring device to ensure that the cable is always in a taut state. If the cable is slack, it is easy to generate impacts when the ship shakes, which will not only damage the cable, but also may affect the stability of the entire mooring system.

[0008] Preferably, a PLC controller is further provided inside the device body, and the annular electromagnet and the second motor are electrically connected to the PLC controller.

[0009] Preferably, the PLC controller receives the magnetic flux generated by the annular coil cutting the magnetic induction line during shaking, and controls the second motor according to the magnitude of the magnetic flux to control the number of turns of rotation of the threaded rod.

[0010] Preferably, the tensioning mechanism includes a fixing ring fixedly connected to the spline bushing. An annular liquid guide frame is sealingly and rotatably connected to the circumferential side wall of the fixing ring. A liquid guide cavity is formed inside the fixing ring. The annular liquid guide frame communicates with the liquid guide cavity. The second anchoring roller is sealingly and rotatably connected to the circumferential side wall of the fixing ring. An arc-shaped groove is formed in the inner wall of the second anchoring roller.

[0013] Compared with the prior art, the advantages of the mooring device for the ocean tugboat cable are as follows: 1.

Through the first anchoring cable and the second anchoring cable on the first anchoring roller and the second anchoring roller, the target ship can be fixed at multiple positions, so that the connection between the ocean tugboat and the target ship is more firm and the stability is improved.

[0014] 2. By arranging the adaptive adjustment mechanism, during use, the shaking condition of the ocean tugboat can be monitored through the moving column. When the ocean environment is relatively harsh (such as strong wind speed and large waves), the distance between the two second anchoring cables on both sides is increased, so that the force on the second anchoring cable during traction of the target ship is more dispersed, avoiding damage to the mooring device. When the ocean environment is relatively stable, when the two second anchoring cables on both sides are used to traction the target ship, the force is more concentrated, so that the traction force generated by the tugboat can be more accurately transmitted to the target ship through the second anchoring cable.

[0015] 3. By providing a tensioning mechanism, when adjusting the distance between the two second mooring cables, the mutual approach or separation of the two L-shaped connecting blocks will drive the two piston blocks to approach or separate from each other, thereby adjusting the distribution of hydraulic oil in the liquid storage space. When the two second mooring rollers move away from each other, the second mooring rollers can rotate relative to the fixed ring to wind the second mooring cables to a certain extent, and the winding degree always corresponds to the distance between the two second mooring rollers, always keeping the second mooring cables in a taut state.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0019] Embodiment: Refer to Figures 1 to 6 , a mooring device for a marine tugboat cable, comprising: The device body 1 is fixedly installed on the towing wheel through fastening bolts; An adjustable multi-point anchoring mechanism 2, the adjustable multi-point anchoring mechanism 2 includes a first mounting block 21 fixedly connected to the center position of the side wall of the device body 1, a first mounting seat 22 is fixedly connected to the first mounting block 21, a first anchoring roller 23 is rotatably connected to the first mounting seat 22, second mounting blocks 24 are slidably installed at positions on both sides of the first mounting block 21 on the side wall of the device body 1, a second mounting seat 25 is fixedly connected to the second mounting block 24, a second anchoring roller 26 is provided on the second mounting seat 25, two support blocks 27 are fixedly connected to the side wall of the device body 1, a driving rod 28 is rotatably connected between the two support blocks 27, the driving rod 28 is fixedly connected to the first anchoring roller 23, spline shafts 29 are provided on both side rod bodies of the driving rod 28, a spline shaft sleeve 210 that cooperates with the spline shaft 29 is rotatably connected to the second mounting seat 25, and the second anchoring roller 26 is installed on the spline shaft sleeve 210, and a first motor 211 for controlling the driving rod 28 is fixedly connected to one of the support blocks 27; Aiming at the problems of single anchoring method and insecure fixation of mooring devices in the prior art, the present invention sets an adjustable multi-point anchoring mechanism 2. During use, the driving rod 28 can be controlled to rotate by the first motor 211, so as to wind the first anchoring cable and the second anchoring cable on the first anchoring roller 23 and the second anchoring roller 26, and adjust the distance between the ocean tugboat and the target ship. Through the first anchoring cable and the second anchoring cable on the first anchoring roller 23 and the second anchoring roller 26, the target ship can be fixed at multiple positions, so that the connection between the ocean tugboat and the target ship is more firm, improving the stability. And because the second anchoring roller 26 is installed on the driving rod 28 through the spline shaft sleeve 210, the second anchoring roller 26 can slide relative to the driving rod 28, and at the same time, the driving rod 28 can always drive the second anchoring roller 26 to rotate, so that the distance between the two second anchoring rollers 26 can be adjusted, and the applicable range is wider.

[0020] Specifically, a first anchoring cable and a second anchoring cable are respectively wound on the first anchoring roller 23 and the second anchoring roller 26. The first anchoring cable is fixedly connected to the side wall of the target ship along the horizontal direction, and the second anchoring cable is fixedly connected to the side wall of the target ship along the inclined direction. Such a connection method restricts the target ship in different directions, further enhancing the fixing effect. The first anchoring cable in the horizontal direction can effectively limit the horizontal displacement of the target ship, while the second anchoring cable in the inclined direction can share a part of the vertical force while resisting the sway of the ship, improving the overall mooring stability.

[0021] The adaptive adjustment mechanism 3 is used to adjust the distance between the two second anchoring rollers 26 according to the marine environment. The adaptive adjustment mechanism 3 includes a control cavity 31 opened inside the device body 1. A moving column 32 is movably installed in the control cavity 31. A plurality of first springs 33 distributed in a circumferential array are fixedly connected between the moving column 32 and the inner wall of the control cavity 31. An annular electromagnet 34 is fixedly connected to the inner wall of the control cavity 31. An annular coil 35 is fixedly connected to the moving column 32. Two sliding grooves 36 are opened on the side wall of the device body 1. Two threaded rods 37 with opposite spiral directions are rotatably connected in the two sliding grooves 36, and the two threaded rods 37 are coaxially and fixedly connected between them. An L-shaped connecting block 38 is threadedly connected to the threaded rod 37. The L-shaped connecting block 38 is fixedly connected to the second mounting block 24 at the corresponding position. A second motor 39 for driving the two threaded rods 37 to rotate synchronously is fixedly connected to the side wall of the device body 1. A tensioning mechanism 4 controlled by the L-shaped connecting block 38 is provided on the side wall of the device body 1 for winding and tensioning the second anchoring cable on the second anchoring roller 26 after the positions of the two second anchoring rollers 26 are adjusted.

[0022] Specifically, a PLC controller is further provided inside the device body 1. The annular electromagnet 34 and the second motor 39 are electrically connected to the PLC controller.

[0023] Specifically, the PLC controller receives the magnetic flux generated when the annular coil 35 cuts the magnetic induction line during shaking, and controls the second motor 39 according to the magnitude of the magnetic flux to control the number of rotation turns of the threaded rod 37.

[0024] Aiming at the problem that the mooring device in the prior art cannot be adaptively adjusted according to the changes in the marine environment, the present invention sets an adaptive adjustment mechanism. During use, the movement of the marine tugboat can be monitored through the moving column 32. When the marine environment is relatively harsh (such as strong wind speed and large waves), the sway amplitude of the tugboat itself is large and the load it bears is large, enabling the moving column 32 to overcome the elastic force of multiple first springs 33 and move significantly. As a result, the annular electromagnet 34 on the moving column 32 cuts the annular coil 35 and generates a large magnetic flux. The PLC controller then controls the second motor 39 to drive the threaded rod 37 to rotate a larger number of turns, causing the two L-shaped connecting blocks 38 to move farther away from each other, increasing the distance between the two second mounting blocks 24, and thus making the distance between the two second mooring cables on both sides wider. When the second mooring cables tow the target ship, the force-bearing range is wider and the force is more dispersed, avoiding damage to the mooring device. When the marine environment is relatively stable, the sway amplitude of the tugboat itself is small and the load it bears is small, causing the annular electromagnet 34 on the moving column 32 to move with a smaller amplitude and generate a smaller magnetic flux. The PLC controller controls the second motor 39 to drive the threaded rod 37 to rotate a smaller number of turns, making the force on the two second mooring cables on both sides more concentrated when towing the target ship. As a result, the traction force generated by the tugboat can be more accurately transmitted to the target ship through the second mooring cables effectively.

[0025] The tensioning mechanism 4 includes a fixed ring 41 fixedly connected to the spline shaft sleeve 210. The peripheral side wall of the fixed ring 41 is hermetically and rotatably connected with an annular liquid guide frame 42. A liquid guide cavity 43 is formed inside the fixed ring 41, and the annular liquid guide frame 42 communicates with the liquid guide cavity 43. The second mooring roller 26 is hermetically and rotatably connected to the peripheral side wall of the fixed ring 41. An arc-shaped groove 44 is formed on the inner wall of the second mooring roller 26. A slider 45 is hermetically and slidably connected in the arc-shaped groove 44, and the slider 45 is fixedly connected to the fixed ring 41. A second spring 46 is provided between the slider 45 and the inner wall of the arc-shaped groove 44. An infusion channel 47 is formed between the arc-shaped groove 44 and the liquid guide cavity 43. A liquid storage tank 48 is fixedly connected to the side wall of the device body 1. Two symmetrically arranged first liquid storage cavities 49 and a second liquid storage cavity 410 located in the middle above the two first liquid storage cavities 49 are formed inside the liquid storage tank 48. A push rod 411 is fixedly connected to the L-shaped connecting block 38. A piston block 412 is fixedly connected to the part of the push rod 411 extending into the first liquid storage cavity 49. The piston block 412 is hermetically and slidably connected to the corresponding first liquid storage cavity 49. Connecting channels 413 are formed between the two first liquid storage cavities 49 and the second liquid storage cavity 410. Liquid infusion pipes 414 are fixedly communicated with both side walls of the liquid storage tank 48. The other ends of the liquid infusion pipes 414 communicate with the inside of the corresponding annular liquid guide frame 42.

[0026] Specifically, a liquid storage space is formed among the second liquid storage cavity 410, the connection channel 413, the first liquid storage cavity 49, the infusion tube 414, the annular liquid guiding frame 42, the liquid guiding cavity 43, the infusion channel 47 and the arc-shaped groove 44, and the liquid storage space is filled with hydraulic oil.

[0027] Aiming at the problem that it is difficult to ensure the tight state of the cable when adjusting the distance of the cable in the prior art, the present invention sets a tensioning mechanism 4. When adjusting the distance between the two second anchoring cables, the mutual approach or separation of the two L-shaped connecting blocks 38 will drive the two piston blocks 412 to approach or separate from each other, thereby adjusting the distribution of the hydraulic oil in the liquid storage space. When the two second anchoring rollers 26 move away from each other, the hydraulic oil can flow into the arc-shaped groove 44, so that the slider 45 in the arc-shaped groove 44 is pushed by the hydraulic oil. Since the first motor 211 is not started at this time, the driving rod 28 will not drive the fixed ring 41 to rotate, so that the second anchoring roller 26 can rotate relative to the fixed ring 41, and the second anchoring cable is wound to a certain extent, and the winding degree corresponds to the distance between the two second anchoring rollers 26 all the time, and the tight state of the second anchoring cable is always maintained, so as to ensure the traction effect of the second anchoring cable on the target ship. When the two second anchoring rollers 26 approach each other, the hydraulic oil flows back, and under the action of the second spring 46, the second anchoring roller 26 rotates in the reverse direction to release an appropriate amount of cable, still maintaining the tight state of the cable.

[0028] In addition, waterproof shells are fixedly connected to the outsides of the first motor 211 and the second motor 39, effectively avoiding the erosion of seawater on the motors, prolonging the service life of the motors, ensuring the stable operation of the motors in the harsh marine environment, and further ensuring the reliable operation of the entire mooring device.

[0029] The functional principle of the present invention can be elaborated through the following operation mode: When the tugboat is ready to moor the target ship, the first motor 211 is started first. The first motor 211 drives the driving rod 28 to rotate. Since the first anchoring roller 23 is fixedly connected to the driving rod 28, and the second anchoring roller 26 is matched with the spline shaft 29 on the driving rod 28 through the spline shaft sleeve 210, the first anchoring roller 23 and the second anchoring roller 26 will rotate synchronously. During this process, the operator can control the rotation direction and number of turns of the first motor 211 according to the initial distance between the tugboat and the target ship, so as to take in and release the first anchoring cable and the second anchoring cable, make the tugboat approach the target ship, and connect and fix the cables to the target ship in the horizontal and inclined directions respectively; When the tugboat is operating at sea, the adaptive adjustment mechanism 3 starts to function. Changes in the marine environment will cause the tugboat to sway. When the tugboat sways, the moving column 32 in the control cavity 31 will move accordingly under the action of the first spring 33. In the event of a harsh marine environment, such as strong winds and huge waves, the swaying of the tugboat intensifies, and the moving column 32 moves a large distance against the elastic force of the first spring 33. At this time, the annular coil 35 on the moving column 32 cuts the magnetic induction lines generated by the annular electromagnet 34 on the inner wall of the control cavity 31, generating a large magnetic flux. After receiving this magnetic flux signal, the PLC controller controls the second motor 39 to start and drive the threaded rod 37 to rotate a large number of turns. Since the two threaded rods 37 have opposite spiral directions and are coaxially fixed, the two L-shaped connecting blocks 38 threadedly connected to the threaded rod 37 will move away from each other, thereby driving the second mounting block 24, the second mounting seat 25, and the second anchoring roller 26 to move away from each other, increasing the distance between the two second anchoring cables, making the force on the second anchoring cables more dispersed when towing the target ship, and reducing the risk of damage to the mooring device; conversely, when the marine environment is stable and the swaying amplitude of the tugboat is small, the magnetic flux generated by the annular coil 35 cutting the magnetic induction lines is small, and the PLC controller controls the second motor 39 to drive the threaded rod 37 to rotate a small number of turns, reducing the distance between the two second anchoring cables and making the traction force transmission more concentrated and efficient; During the process of adjusting the distance between the two second anchoring cables, the tensioning mechanism 4 ensures that the second anchoring cables are always taut. When the two L-shaped connecting blocks 38 move away from each other, the push rod 411 on the L-shaped connecting block 38 drives the piston block 412 to slide in the first liquid storage cavity 49, causing the hydraulic oil in the first liquid storage cavity 49 to flow into the second liquid storage cavity 410 through the connecting channel 413, enter the annular liquid guide frame 42 through the liquid infusion pipe 414, and then enter the arc-shaped groove 44 on the inner wall of the second anchoring roller 26 through the liquid guide cavity 43 and the liquid infusion channel 47. The hydraulic oil pushes the slider 45 in the arc-shaped groove 44, and with the cooperation of the second spring 46, the second anchoring roller 26 rotates relative to the fixed ring 41 to wind up the second anchoring cable. Moreover, as the distance between the two second anchoring rollers 26 increases, more hydraulic oil flows into the arc-shaped groove 44, and the winding degree of the second anchoring cable increases accordingly, always remaining taut. When the two L-shaped connecting blocks 38 move closer to each other, the hydraulic oil flows in the reverse direction, and the second anchoring roller 26 rotates in the reverse direction under the action of the second spring 46 to release an appropriate amount of cable to maintain the taut state.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
